The terpolymeric resins were prepared by base catalyzed polycondensation of p-hydroxybenzaldehyde, resorcinol and formaldehyde. Resin obtained by molar monomer composition, p-hydroxybenzaldehyde: resorcinol: formaldehyde as 1:1:3 was abbreviated as PHBRF-I and that prepared by 1:2:4 composition was abbreviated as PHBRF-II. These resins were characterized by physicochemical methods such as elemental analysis, UV-Vis, IR and NMR. ion- exchange study was carried out with Cu 2+ , Zn 2+ , Ni 2+ , Co 2+ , Pb 2+ & Cd 2+ by batch equilibrium method. The rate of metal ion uptake by PHBRF-II terpolymeric resin was higher than that of PHBRF-I. Effect of pH and electrolytes under specified condition were also studied. The terpolymeric resins show high selectivity for
